The Radium Engineering high flow fuel filter has a 3 piece body that is CNC machined from 6061 aluminum and Type-II anodized for maximum corrosion resistance. Both removable end caps feature large -10AN ORB female threaded ports for high flow plumbing.

The fuel filter comes preassembled with FKM O-ring seals for all fuel types including gasoline, diesel, methanol, ethanol, and alcohol blends such as E85. High fuel pressures < 150psi can safely be used with negligible pressure drop.

The filter features a large 4.2"x1.75" element maximizing flow without sacrificing filtration. The large elements also hold a lot of contaminants without becoming a restriction, resulting in a very long service life.

The official BOSCH Fuel Injector filtration specification states:

"Recommended filter quality: nominal rating 5um, minimum 82% capture efficiency according to ISO/TR 19438; dirt particles > 35um are not permissible." 

The Radium Engineering 18-0025-05 element (from 20-0220-05 filter) has a capture efficiency of 99.9% at 6 micron.
